The young Sheldon Brown on his J.C. Higgens

1950s J.C. Higgins 3-speed
This Austrian bike, originally sold by Sears, was my first multi-speed bike, and the first bike that I put together from parts scrounged from the town dump. It only had a rear hand brake, but it was a considerable improvement over the Rollfast. (Although I still kept the Rollfast for riding in the woods.)
